CHAIR-SEAT AND CHAIR.

SPECIFICATION forming part of Letters Patent No. 317,382, dated May 5,1885.

. Application filed January 24, 1884. (No model.)

.To aZZ whom/it may concern:

Be it known that I, FREDERIC LATULIP, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Chair Seats and Backs, of which the following, taken inconnection with the accompanying drawings, is a full,

clear, and exact description.

This invention has for its objects to provide an improved seat or backfor chairs, settees, and other like articles, which will be strong anddurable and ornamental, and which can be supplied to the trade atreasonable cost in such form as to be conveniently secured to an articleof furniture, as more fully hereinafter described.

Heretofore chair and settee seats and backs have been constructed ofplain sheets'of vulcanized caoutchouc or rubber, or of such sheetspunched or perforated mechanically after vulcanization, and also .ofpaper or pasteboard peculiarly treated and embossed to give it anornamental configuration. The articles as thus constructed do notpossess the requisite qualities of a chair seat or back, as, unless madevery heavy or of very heavy material, they soon wear out or give way,and this is especially the casein the perforated caoutchouc or rubberseats and backs,the perforations, while serving to lighten the articles,materially weakening the same and rendering them extremely liable tobreak down.

My invention further has for its object to economize material withoutdetracting from the strength of the article, as more fully hereinafterspecified. By my invention these objections are wholly obviated, and alight,

strong, durable, and ornamental article is produced.

In the drawings, Figure l is a plan View of a chair-seat constructedaccording to my invention. Fig. 2 represents a similar view of amodification of the same. Fig. 3 is atransverse section taken on theline so :0 of Fig. 2; and Fig. 4 is a view, partly in elevation andpartly in section, showing the press and the means of forming myimproved article.

In carrying out my invention the caoutchouc, rubber, or gutta-percha ina raw state,

with a suitable admixture of sulphur or other forced into and takes theconfiguration of the faces of the mold. The said faces are formed withindented grooves D, crossing or intersecting each other, and formingcorrespond ing ribs, E, in the molded material. NVhere extreme lightnessand provision for ventilation is desired in the finished article, thefaces of the molds between the intersecting grooves are formed withprojections, which,

leave openings F between the intersecting ribs of the article, asindicated in Fig. 2 ot' the drawings. When thus formed, the material,which would otherwise fill the spaces between the intersecting ribs, isforced or crowded up to form such ribs, thus saving the material andeffecting an important ad- .vantage by lessening in cost withoutimpairing the strength of the article. The article is then subjected tothe usual vulcanizing temperature while in the molds, by means of whichit becomes hardened, losing its plasticity, but preserving its shape. Asthus constructed the articles possess material advantages over otherarticles of this class, for the reason that, being formed under powerfulcompression, the parts are compacted, and possess the greatest possiblestrength, the intersecting ribs re-enforcing and adding to the strength,while the openings, which render the article extremely light, do notdetract from its strength, as in the case of punched or cut apertures.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, attesting witnesses, at Syracuse, in the county isofOnondaga, in the State of New York, this A seat or back for chairs orother articles 11th day of January, 1884.
